Christine,
There are many issues within your email and I will do my best to address the questions as I read them. First of all, to me a horse is not broke if he is afraid of you walking around behind him. I would not pursue riding him until I could resolve these issues on the ground first. Horses have a hard time allowing someone past their shoulder—this is a matter of vulnerability and trust. He is comfortable with you in front of him because he can defend himself well from that position. To allow you into his flank and behind him takes a lot more trust on his part. Keep working with him on the ground to build that trust and he will eventually let you into his backside. I would want to make sure this horse is totally desensitized to all stimuli on his hindquarters (touch, ropes, etc.) before going further with his riding.
As you have no doubt figured out by now, Mustangs can be much more of a training challenge than a domesticated horse. BTW- it may not have been because of neglect or abuse that this horse was returned; it might also have been because the horse was too difficult to train. The instincts of Mustangs are much keener, their herd behaviors much more engrained and the trauma that they endure in the round-up can sometimes be devastating. I urge you to observe extreme caution with this horse; do not EVER consider his gestures as a bluff; always take them seriously.
Unfortunately, in your first session in the round pen, your horse challenged your authority and you backed down, so in his mind (and mine), he is dominant over you. Basically what happened is that you put him to work in the round pen to show him that you controlled his space and therefore are the dominant one. He stopped and looked at you in challenge to your control. Probably at that point, you showed some uncertainty in your body language and your horse saw that as a weakness and figured it was an opportunity to prove his point and show you that not only are you not the boss of him, but that he is in fact the boss of you. Because you backed down at that point, you proved him right.
It is not at all uncommon for a horse to charge you in the round pen and I address this in my video, Round Pen Reasoning, which also contains a lot of information on horse behavior and a step-by-step process to follow in round pen training. Not all horses will charge, but sometimes the most unlikely horse will challenge you in this way (Mustangs are more likely but any horse is capable, including the most docile). This is a VERY dangerous situation and people have been killed when charged by a horse in the round pen. There has been at least one such death this year with a Mustang in the round pen, that I personally know of, and that involved someone that was experienced with Mustangs and with round penning.
This is one reason why, as explain in the video, I will NEVER allow a horse to turn toward me in the beginning stages of round pen work. Always make him turn away from you, because on occasion, when a horse turns toward you, he will charge you. Although usually it is a bluff, it would be foolish to assume that, since your life may be on the line. When the horse charges, you must always take immediate defensive action; that is one reason why you always go into the round pen with a ‘weapon’ of some sort (a rope, stick, flag, whip). You will use your ‘weapon’ to deflect the horse’s charge by waving or striking right at his head, in order to turn him away from you. This may sound like an extreme measure, but until you have been charged by a horse in the round pen, it is hard to understand what an extremely dangerous situation this is.
Given the previous experience of this horse in the round pen, his history and given your lack of experience in training horses, I would highly recommend that you get a professional to help you work through these issues with your horse. With some training on your part and the horse’s part, and good supervision, you should be able to resolve this problem. But this is a dangerous scenario and I urge you t use caution and seek professional help.
